Most action controls are aimed at preventing undesirable behaviors. The exception is action accountability controls. Although action accountability controls are designed to motivate employees to behave appropriately, it cannot be verified whether the appropriate actions were taken until evidence of the actions is gathered. However, if the evidence gathering is concurrent with the activity, as it is with direct supervision, then action accountability control can approach the desired state of prevention of undesired actions. Table 3.2 shows examples of common forms of action controls classified according to whether their purpose is to prevent or detect problems.
